Services
Sash Window Refurbishment
Our sash window refurbishment service restores timber frames to their original condition using Tricoya wood for durable repairs. We address decayed sills, rotten beading, and cracked glass while preserving historical authenticity. This service includes an 8-year paintwork guarantee and 20-year warranty on repaired parts, ensuring long-term performance for period properties.
Double Glazing Retrofitting
Double glazing retrofitting enhances energy efficiency by installing slim-profile vacuum units into existing sash windows. This process maintains the original appearance while reducing heat loss and noise. Ideal for listed buildings, it offers thermal performance equivalent to triple glazing without altering historical features.
Listed Building Restoration
Specialised restoration for Grade 2 listed properties, combining traditional methods with modern materials. We perform like-for-like repairs to preserve architectural integrity while improving functionality. Services include frame reinforcement, draught-proofing, and vacuum glazing installation approved by conservation officers.
Bay Window Repair
Bay window restoration addresses structural decay and draught issues without full replacement. Our process includes sill replacement, frame repairs, and weatherproofing. This service extends the lifespan of custom-designed bay windows in historic buildings while maintaining their aesthetic character.
Draught-Proofing
Draught-proofing seals gaps in sash windows to improve thermal efficiency and reduce energy bills. Combined with glazing upgrades, this service enhances comfort while preserving original window mechanisms. It is particularly effective for period properties requiring minimal visual alteration.

I appear to be an outlier here but my experience with Chameleon (also Scott James Sash Windows - basically the same company as SashCare, Chameleon Windows Decorators & CDC Restoration) is far from positive. They can be relied upon to be in complete denial if there is a problem with their, let us say, unorthodox work methods. One thing they do specialise in is gaslighting. I am not alone in this opinion. Several UK glass suppliers will not deal with them anymore because of their fear of bringing their brand into disrepute. Caveat emptor.

After eight years, I'm back as a returning customer, and I'm thrilled to say that the service remains outstanding. A big thank you to Victoria and Alex for your excellent assistance and communication. I also want to extend my gratitude to the entire team for their meticulous craftsmanship and care in restoring my windows, culminating in a fantastic paint finish. I highly recommend Chameleon to anyone in need of window restoration or a stunning paint job.

Chameleon are a fantastic company to deal with. If you have enough sash windows which need refurbishing (there is a minimum order), then I can't recommend them highly enough. The managers are knowledgeable, courteous and professional, and their team of joiners are hard-working, efficient and speedy, so the work itself was remarkably painless. We are delighted with the result.

Alex and the team have restored our 20 year old sash windows so they look brand new. The team worked non-stop to complete it and made sure everything was to an excellent standard. Thank you. Rob

Now three years after the windows were repaired and redecorated, they still look like they were painted yesterday. Easy and straightforward company to deal with.

We had an excellent experience with Chameleon Decorators. The work was completed on time and to a very high standard throughout, all at a fair price. Would have no hesitation in providing a recommendation. Please note that the team work on the exterior only so you will need to factor in an internal job also!
